Yi Mo robot of the present invention two-freedom shoulder joint drive unit, is characterized in that: the first steering wheel is fixed on shoulder and connects on pedestal, and its output shaft drives the first drive, and the first drive is fixedly connected with shoulder joint by the first dowel screw assembly.

Yi Mo robot of the present invention two-freedom shoulder joint drive unit, is characterized in that: the second steering wheel is fixed on postbrachium and connects on pedestal, and its output shaft drives the second drive, and the second drive is fixedly connected with shoulder joint by the second dowel screw assembly.

Yi Mo robot of the present invention two-freedom shoulder joint drive unit, is characterized in that: shoulder connects pedestal and can rotate around the first steering wheel axis direction, and postbrachium connects pedestal and can rotate around the second steering wheel axis direction.

Yi Mo robot of the present invention two-freedom shoulder joint drive unit, is characterized in that: the rotation of the first steering wheel and the second steering wheel forms interaction relation, and the angle that they rotate respectively is n1, n2, wherein the positive number that set by user of n2=k × n1, k.K can be preferably 0.618 or 0.475.

The invention has the beneficial effects as follows: the present invention, as a kind of Yi Mo robot two-freedom shoulder joint drive unit, can realize clothing mould robot shoulder two-freedom and rotate, can meet the requirement of robot to shoulder freedom of movement.

(4) accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is further described.

Accompanying drawing 1 is outside drawing right view of the present invention

Operation principle of the present invention is as follows: after the first steering wheel 6 rotates, output shaft drives the first drive 5 to rotate, by the first dowel screw assembly 4, first drive 5 is fixedly connected with shoulder joint 2, shoulder connection pedestal 1 is connected by the first roller assembly 7 with shoulder joint 2, can realize shoulder connection pedestal 1 like this and rotate around the first steering wheel 6 axis.

After second steering wheel 10 rotates, output shaft drives the second drive 9 to rotate, by the second dowel screw assembly 11, second drive 9 is fixedly connected with shoulder joint 2, postbrachium connection pedestal 3 is connected by the second roller assembly 11 with shoulder joint 2, can realize postbrachium connection pedestal 3 like this and rotate around the second steering wheel axle 10 line

Therefore, two steering wheels work simultaneously, just can realize the rotation of two frees degree.

In order to improve the efficiency of rotation, the rotation of the rotation of the first steering wheel 6 and the second steering wheel 10 is formed interaction relation, arrange the proportionate relationship k of the rotational angle n1 of the first steering wheel 6 and the rotational angle n2 of the second steering wheel 10, wherein k is positive number, and n2=k × n1.That is, when the first steering wheel rotates as a angle by user, the second steering wheel corresponding rotation k × a angle, thus improve rotational efficienty.When arranging k and being 0.618 or 0.475, after two frees degree can be made to rotate, the shoulder of Shi Yi mould robot can present preferably visual impression, improve the facility that user arranges Yi Mo robot.

Above content is in conjunction with concrete preferred embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
